An important text for understanding Ovidian reception in the Middle Ages is John of Garland’s Integumenta Ovidii, a 13th century Latin poem that allegorizes the myths of Ovid’s Metamorphoses. The Integumenta has received little scholarly attention, with the most recent edition having been published in 1933. This thesis seeks to improve upon the understanding of the poem’s text, transmission, and allegorical interpretations by closely studying the first 118 lines, Garland’s allegorization of Book 1 of the Metamorphoses. The project includes collations of six previously unexamined manuscripts, an edition considering readings from the new manuscripts and from the ten additional manuscripts recorded in past editions, an English translation, an introduction, and a commentary discussing the textual, contextual, and interpretive issues of the poem
